pmppm R Documentation
Plus/minus parts per million
Description
It shouldn't be hard to translate a point mass into a mass window bounded by
spectrometer accuracy.
Usage
pmppm(mass, ppm = 4)
Arguments
mass
A length-1 numeric representing the mass of
interest for which a mass range is desired.
ppm
The parts-per-million accuracy of the mass spectrometer on which
the data was collected.
Value
A length-2 numeric representing the mass range requested
Examples
pmppm(100, 5)
pmppm(1000000, 5)
pmppm(118.0865, 2.5)
pmppm(892.535313, 10)
